Fig. 5, is a detail perspective view of one of the pins made use of for feeding the hoop through the machine.

In carrying out my invention I provide a suitable frame consisting of two side mem bers 6, and 7, each provided with a suitable journal bearing 8 in which is supported a shaft or spindle 9, on this shaft or spindle is located a large gear wheel 10 which is de signed to mesh with a gear pinion 11, mounted on the shaft 12, which is also supported in bearings 13, formed in each member constituting the frame. On the projecting end 14 of the shaft 12 may be applied a crank-handle by which the device may be placed in operation by hand or on said shaft may be located a pulley by which the machine may be driven by power.

On the shaft 9 and located centrally between the'members 6 and 7 constituting the frame is located a cutting member composed of two cutting disks 15 and 16, the outer periphery being formed to a knife edge, the same if desirable spaced apart by means of from the hub 18 by which the core is supportedon theshaftfi; 1 In thecore A and at suitable 7 intervals apart Iprovide boresoropenings 19in which are projecting ononesideiand ifi on the opposite side of the center core in "@POSiblOIirflS that HOQiSrLiITING ivihciiniii. ff

a center core 17*, which,is constru ted pref erably initlm manner that sho-wnin-sectional view of Fig. 4, the core radiating,

'ada ptedto be inserted feeder pins .20, the horizontal portions of the pins: passing intothe bores while the right angular or vertical portion 22 is directedtowardthe peripheryof the core permittedto. be seated :in grooves 23 formed in thesides of the oore, the ends of saidipins being wedge shape as: that indicated by -the numeral .24 showneinFig-fi;

These pins as" shown-in tile -illustration are arranged preferably 12 number, .6

shown in 1 the illustration :1 of Fig. 2. r The projectingflangeends of these pins arearranged tofit snuglyagainst itheiinnerface' I of the cutting Ldiskand arrangedto contact with the-center strip ofth'ehoop asitlie same is being cut or split by the disks. And by these pins the hoop is fed through themachine.

In the frame and directly beneath the cutting disk is located a grooved roller 25, this is also mounted on a short shaft or a pair of projecting lugs which havebearing in the journals 26 formed in the frame. The surface of the roller is provided with a pair of grooves 27 as that shown in Fig. 4 and in which the cutting edge of both disks. project. This roller revolves by means of the frictional contact of the hoop during the rotation of the machine.

. In order to permit the hoop to freely move through the machine and-t0 avoid friction I provide in the frame a pair of said frictional rollers 28, one supported on each member of the frame and supported between projecting integral lugs 29 formed on each .100 frame, the rollers passing through slots formed in such members and of such depth as topermit the periphery of each frictional roller to be shortly beyond the alinement of the inner surface of each frame. The position being clearly illustrated in Fig. 2. o

On the frame and in advance of the cutting disks .Iplace a cross bar 30 which bar is firmly fastened on each side member and straddling the same and to this bar. is a depending curved guide member 3 l'the free end of the edge to almost contact with the periphery of the core yet out of contact with the feeder pins. 1 The purpose of this guide is to direct the center portion of the hoop after the same has been cut f fol;

lowing the core after having been connected with by the feederpins'which in the "opera tion are partly sunk into" the hoop in order.

to feed the same forward. The frame is also providedwith a table. 3.2 on which the hoop is placed for feeding the sameagainst' the cutting disks. Y Q V, i

. The hoops to be cut by this machine are generally of such character as are vnot fitfor i a 1. In a-hoop splitting machine the comvbination of a suitable frame of a pair of rotating splitting disks mounted therein, and means operating in" conjunction-with the rotating cutting disks for/feeding hoops through the machine ,to be split inthree sections, substantially as specified. L

. 2. Ahoop, splitting machine comprising a frame, a rotating core, a pair of circular splittingxdisksconnectedto said core and suitably spaced apart, a pluralityoffeeder pins carried .bythe core and between the cutting disks, .and means for rotating the core and splitting disks for splitting. a barrel hoop into three sections, substantially as specified.

3. A machine of the class described comprising a suitable fr'ame a rotating core mounted therein, a pair of circular splitting disks carried by the rotating core, a grooved roller supported in the frame below the rotating core and in proper relation vwith the splitting disks, means carried by the core for feeding the hoop between the splitting disks and the. grooved roller and a; guide in connection with the core for directing the split sections. of. the hoop away from the core when the same has been cut,

substantially as specified.

4. A machine of the-class described comprising a suitable frame, a pair of splitting disks rotatably mounted therein, feeder pinslocated between said splitting disks which pins contact with the material to be split for feeding the same, a grooved roller carried; in the frame below the splitting disks and having its grooves located in proper relation with the splitting disks over which the material tobe cut isplaced and-a guide mechanism for directing the split ,section of thevhoop, away from the splitting disks.

In testimony whereof, I have signed my name to this specification, in presence of two.
